Biochar has high potential applicability for use in controlling agricultural non-point source pollution and greenhouse gas emissions because of its well-developed pore structure and high content of surface oxygen-containing functional groups, ash, and inorganic minerals. Uncertainty concerning the?effects of biochar on characteristics of the nitrogen cycling microbial community is a key problem facing its use for controlling non-point source pollution and improving soil quality.?In this study, the effects of biochar on soil nitrifying and denitrifying microorganisms were reviewed in terms of biochar’s diversity, the amount added, and environmental conditions. This review found that high temperature pyrolyzed biochar had better effects on soil nitrogen cycling microorganisms than low temperature pyrolyzed biochar. The sources of the biochar used, amount of biochar added, and soil pH had greater impacts on soil nitrogen cycling microbial communities. Organic fertilizers were able to improve the carbon utilization and activity of nitrogen cycling microbial communities more than conventional chemical fertilizers could. Environmental pollutants, such as polycyclic aromatic hydrocarbons, phenolic compounds, and heavy metals, are not conducive to the survival of nitrogen cycling microorganisms. Given recent advances in molecular biotechnology, future studies of the impact of biochar on soil nitrogen cycling microorganisms should be combined with a variety of molecular ecological techniques and stable isotope probe technology.?The influence of pyrolysis temperature and the amount of biochar used on soil nitrogen cycling microorganisms can also not be ignored. The differential effect of aged biochar on pollutants and nitrogen cycling microorganisms should be confirmed in long-term field trials.
